It is often said that the United States is the fattest country in the world. Is it? Does it depend on how one measures fatness?

1It probably does depend how you measure. There's the proportion of people that are obese (used in the CIA World Factbook). However, that doesn't tell you how obese they are. Conceivably, in one country many people could be just over the obesity line, while in another they're far more obese than that cut-off.– Matthew FlaschenMar 5, 2012 at 8:51

@Matthew yes, that's why I welcome more answers with more definitions of "fattest country".– Sam I AmMar 5, 2012 at 15:32

1I've also heard claims that Australia is the second fattest country, behind the US. This also seems to be dubious, based on the answers here.– Andrew GrimmMar 6, 2012 at 7:44

This also depend how small a country do you consider. Should you really consider small island nations with less than 100K residents in this statistic?– vartecMar 14, 2012 at 10:21

The World Factbook is a reference publication by the United State's Central Intelligence Agency.
The World Factbook is prepared by the Central Intelligence Agency for the use of US Government officials, and the style, format, coverage, and content are designed to meet their specific requirements. Information is provided by Antarctic Information Program (National Science Foundation), Armed Forces Medical Intelligence Center (Department of Defense), Bureau of the Census (Department of Commerce), Bureau of Labor Statistics (Department of Labor), Central Intelligence Agency, Council of Managers of National Antarctic Programs, Defense Intelligence Agency (Department of Defense), Department of Energy, Department of State, Fish and Wildlife Service (Department of the Interior), Maritime Administration (Department of Transportation), National Geospatial-Intelligence Agency (Department of Defense), Naval Facilities Engineering Command (Department of Defense), Office of Insular Affairs (Department of the Interior), Office of Naval Intelligence (Department of Defense), US Board on Geographic Names (Department of the Interior), US Transportation Command (Department of Defense), Oil & Gas Journal, and other public and private sources.
The World Factbook defines Obesity - adult prevalence rate as follows:
This entry gives the percent of a country's population considered to be obese. Obesity is defined as an adult having a Body Mass Index (BMI) greater to or equal to 30.0. BMI is calculated by taking a person's weight in kg and dividing it by the person's squared height in meters.
For countries where this information is published in the World Factbook, The United States of America is ranked #18 in the world with 33% of the population obese. Notably, some Middle Eastern and small island counties have higher obesity rates.

United States is now down to 18th on that list, so the link no longer matches the table– DavePhDApr 17, 2015 at 18:28

All of the countries above the US, not including Egypt, put together, are pretty small, IIANM - probably less than 5 million people between all of them put together, to make a guesstimate. So in a way, the answer should be "There's another one major country with more prevalent obesity, which is Egypt". Jul 16, 2018 at 9:33

No, the dubious privilege goes to the small island of Nauru where around 80% of the population are obese (as of 1994).
Obesity in Nauru is a major health concern for the nation. According to Forbes, Nauru is the world's fattest country with 94.5 % of the inhabitants at an unhealthy weight. The obesity rate is roughly 80%. Due to little arable land, much of local diet is processed food imported from elsewhere. Cultural and social ideologies contribute to this as well, obesity is seen as sign of wealth and power. The nation's children are also known to lead more sedentary lives.

Interestingly, Nauru is not mentioned in the list linked to by Sam I Am, as it only lists 70 countries. Maybe it got grouped with Australia. Mar 6, 2012 at 7:43

1@AndrewGrimm, I noticed that too. It wasn't grouped with Australia, as Nauru has an entry in the Factbook. My guess is the CIA didn't find a source they felt was reliable enough for some countries. Their FAQ states "The Factbook staff uses many different sources to publish what we judge are the most reliable and consistent data for any particular category. Space considerations preclude a listing of these various sources."– Sam I AmMar 6, 2012 at 15:21
The USA is currently the fattest developed country in the world.
It is possible that when people talk about the US being the fattest country, they are referring only to developed countries. In which case the US currently comes in first place.
The Organisation for Economic Co-operation and Development recently released a report that puts The USA as the most obese developed country, with Australia coming in 5th and Finland coming in 10th.
It's interesting to note that this fluctuates. At one point Australia was ahead of the US in obesity rankings.
Overall, Nauru is currently the country with the highest rate of obesity, as Sklivvz shows in his anwer.
This may be in part to "fattening rituals" which are a part of the Nauru culture.
Fattening rituals were also practised in Nauru where fattening was associated with beauty and fertility. Young women of the chiefly class were the central focus of deliberate fattening, particularly at the time of first menses, such practices continuing past child-bearing into middle age. Some young men also participated in these fattening rituals, as preparation for boxing competitions between districts.

1I don't know, Saudi Arabia looks pretty developed to me, and has comparable levels of obesity according to the top answer, coming out slightly ahead of the US.– RomanStSep 22, 2014 at 0:11

@romkyns that's why I added the currently qualifier in my answer. Sep 22, 2014 at 7:22
